Fig. 8 A to 8E are the flowage structure figure of the gas pump start shown in Fig. 5 A and 5B.Fig. 7, Fig. 8 A to Fig. 8 E are referred to,
The start process description of the gas pump of this case is as follows.When gas pump 22 carries out start, piezo-activator 223 is by voltage actuation
With support 2233 as fulcrum, the reciprocating vibration of vertical direction is carried out.As shown in Figure 8 A, when piezo-activator 223 is caused by voltage
When moving and vibrating downwards, it is light, thin laminated structure to be due to resonance plate 222, is when piezo-activator 223 vibrates, to be total to
Shake piece 222 also can with resonance carry out vertical reciprocating vibration, the as part of the corresponding central recess 221c of resonance plate 222
Also can with flexural vibrations deformation, i.e. the part of correspondence central recess 221c is the movable part 222a for resonance plate 222, be with
When piezo-activator 223 is bent downwardly vibration, now the movable part 222a of the corresponding central recess 221c of resonance plate 222 can be because of gas
Body bring into and push and the vibration of piezo-activator 223 drive, and as piezo-activator 223 is bent downwardly vibration shape
Become, then gas is entered by least air admission hole 221a on inlet plate 221, and conflux round 221b to be pooled to through at least one
Center central recess 221c at, then via the hollow bore 2220 being correspondingly arranged with central recess 221c on resonance plate 222 to
Under flow into first chamber 220.Thereafter, due to being driven by the vibration of piezo-activator 223, resonance plate 222 also can be total to
Shake and carry out vertical reciprocating vibration, as shown in Figure 8 B, now the movable part 222a of resonance plate 222 also with downward vibration,
And attach contact at piezo-activator 223 suspension board 2231 convex portion 2231a on, make the convex portion 2231a of suspension board 2231 with
The spacing of the chamber that confluxes between outer region and the fixed part 222b of the both sides of resonance plate 222 will not diminish, and by this resonance
The deformation of piece 222, to compress the volume of first chamber 220, and closes the middle flow space of first chamber 220, promotes in it
Gas is pushed and flowed to both sides, and then passes through stream downwards by the space 2235 between the support 2233 of piezo-activator 223
It is dynamic.Afterwards, as shown in Figure 8 C, the movable part 222a of resonance plate 222 is bent upwards vibration deformation, and returns back to initial position, and
Piezo-activator 223 is driven to vibrate upwards by voltage, the volume of so same extruding first chamber 220, only now due to pressure
Electric actuator 223 is upward lifting, so that the gas in first chamber 220 can flow towards both sides, and then drives gas to hold
An at least air admission hole 221a of the continuous ground from inlet plate 221 enters, then flows into the chamber that central recess 221c is formed.It
Afterwards, as in fig. 8d, the resonance plate 222 is resonated upwards by the vibration of the upward lifting of piezo-activator 223, now resonance plate
222 movable part 222a also with upward vibration, an and then mitigation of gases at least air admission hole constantly from inlet plate 221
221a enters, then flows into the chamber that central recess 221c is formed.Finally, as illustrated in fig. 8e, the movable part of resonance plate 222
222a also returns back to initial position.Thus implement aspect and understand that, when resonance plate 222 carries out vertical reciprocating vibration, being can
By it with the gap h between piezo-activator 223 to increase the ultimate range of its vertical displacement, in other words, in two structure
Between gap h is set the resonance plate 222 can be produced upper and lower displacement by a larger margin when resonance.Therefore through this gas pump
Barometric gradient is produced in 22 runner design, makes gas flow at high rates, and enter the resistance difference of outgoing direction through runner, by gas
Transmitted to outlet side by suction side, to complete gas conveying operation, even if in the state of outlet side has air pressure, still having the ability to hold
It is continuous to push air into water conservancy diversion chamber 200, and Jing Yin effect is can reach, the start of gas pump 22 of Fig. 8 A to 8E is so repeated, i.e.,
Gas pump 22 can be made to produce the gas transport of an ecto-entad.
